EYEGLASSES.

Specification of Letters Patent.

Patented mm; 10, 1908.

- Application filed February 5, 1907. Serial No. 355,854.

To all whom it may concern:

Be it known that I, FRED M. VANCE, a citizen of the United States, residing at Geneva,

' -in the county of Ontario and State of New York, have invented new and useful Improvements in Eyeglasses, of which the folowing is a specification.

The invention relates to an improvement in eyeglasses and particularly to a self-adjusting nose guard therefor, which will read- 11y accommodate itself to irregularities of,

the nose of the wearer and properly secure the glasses in lace.

The main 0 ject of the present invention is the production of a nose guard which is so connected to the guard plate as to provide for such independent movement of the guard as will permit it to accommodate itself to any irregularities of the nose of the wearer.

The invention will be described in the following specification, reference being had particularly to the accompanying drawings,

in which:

Figure 1 is a view infrear elevation of a pair of eyeglasses provided with my improved self-adjusting guard, Fig.- 2 is an enarged sectional View on the line 22 of Fig.

. 1, Fig. 3 is'a detail view with the guard proper a view in elevation of 'a guar artly in section, illustrating the connection hetween'the guard and guard late, Fig. 4 is d plate, Fig. 5 is an enlarged vertical section through the guard the cooperating head of the guard plate eing shownin place.

-In carrying out the details of the present invention I make no material changes in the eyeglass, as at present constructed, be-

' yond the articular arrangement of the nose guard, an therefore, it is to be understood that the present invention is applicable to any form of eyeglasses using nose guards.

vSL1

In its essential details the present invention com rises a guardplate or arm 1 designed to e secured to the post 2 of. an ordinary eyeglass and projecting. rearwardly therefrom to a proper length torterminally ort the nose guards in pro er position. t is to be understood th'at;t e'particular formation of the arm .1, With'th'e. exception of the guard receiving-end is immaterial so far as the present invention is concerned,

shaped as to provide for their proper app and said' arms are to'be so constructed and lication to avoid interference with any 0t e'r portion of the eyeglass structure in the event such is necessary. The inner or free terminals of each arm 1 are reduced in width to provide a head 3, the projection of the arm immediately in rear of the head forming an ofi'set point or shoulder 4.

The nose guard, or more properly speakby impressing the material of the fplate under a suitable die, and the bottom 0 the socket is formed with a slot 6, of greater 1e th and width than thesimilar dimension of t '0 head 3 of the arm.

In assembling the parts the head 3 of the arm is passed through the, slot 6 in the guard plate, and the free terminal of said head is upset beyond the bottom of the socket 5. The (guard plate and arm are thus firmly secure against separation, while the o erative dimensions of the openings 6 the head 3 provide in eiiect a swivel connection between said guard plate and arm, whereby the guard plate is pernutted such independent mo cement relative to the arm as would insure the accommodation of the guard late t0 any irregularities of the nose 0 the. wearer.

The connection of the arm and guard plate is particularly efiective for the reason that there is no projection on the face of the uard plate to interfere with thepad, and sai connection requires, after formation of the parts,

simply the upsetting of the head of the am.

As the connection provides practically unlimited self-adjustment of the nose guards; it

structure, the terminal of the arm bem cut away on its upper edge to form a head 0 less vertical dimensions than the arm terminal and to provide a projection from the upper edge of said terminal-1n rear of the head, and a guard plate to engage the arm, said plate being formed with a socket by ofisetting the material of the plate, the socket being of greater dimensions than the similar dimensions of the head, the projection serving to prevent movement of the upper portion of the guard p1 ate toward the adjacent lens beyond the vertical.

2. A nose guard for eyeglasses comprising a guard arm to be secured to the eyeglass structure, the terminal of the arm beingcut away on its upper edge to form a head of less vertical dimensions than the terminal and to provide a pro ection from the upper edge of said terminal in rear of the head, and a guard plate to engage the arm, said plate being ormed with a socket by offsetting the material of the plate, the upper portion of the l socket being adapted to bear against the ro- 1.5
